Physical processes associated with Green Noctiluca Blooms





The observations found that, surface currents have influence in lifting phytoplankton groups to surface waters. This is well evident from Empirical Orthogonal Teleconnections.

Trophic dynamics of SubSurface layers
The LVM models suggest that the Trophic dynamics are efficient in energy transfer
The nutrient dynamics on the subsurface are stable
The temperature and light factors are optimum
The subsurface blooms can be expected more frequent in future warming scenarios
Global density changes, settling velocities and time shifts in blooms
Phytoplankton response to climate change
Global density changes, settling velocities and time shifts in blooms
SST variations in decadel scale over four weeks of March
SCM strengthen and warming seasons on various years

Warming effects on Noctiluca distributions
Warming -Stratification links to Noctiluca are well reflected in spatial distributions
The Northern Hemisphere seems to be subjected to more than south
The Land locked areas are more prone to the occurrence of Noctiluca blooms due to nutrient availability and efficient stratification

Early occurrence of Phytoplankton blooms in NEAS ?
Early occurrence of Phytoplankton blooms in NEAS ?












The wavelet decomposition in low frequencies (D7 and D8 waves) are strongly concurrent between the surface chl-a and pycnocline depth
The periods seems to be frequent within a range of 128 & 256 days
The changes in pycnocline are significant in NEAS because the nutrient -depleted surface waters enrich by pycnocline due to wind mixing
Wavelet Coherence: pycnocline depths vs surface chlorophyll
Wavelet Coherence: pycnocline vs SCM
